Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42338, here are decompositions:
- 7 + 42331 = 42338
- 31 + 42307 = 42338
- 151 + 42187 = 42338
- 157 + 42181 = 42338
- 181 + 42157 = 42338
- 199 + 42139 = 42338
- 277 + 42061 = 42338
- 379 + 41959 = 42338
Showing the first eight; more decompositions exist.
